 #### Check links from a local markdown folder (recursive)
 
-Avoid using `find -exec` because it will swallow the error from each consecutive run.
-Instead, use `xargs`:
+This checks all files in folder `./docs` with file extension `*.md`:
+
 ```shell
-find . -name \*.md -print0 | xargs -0 -n1 markdown-link-check
+markdown-link-check ./docs
 ```
 
-There is an [open issue](https://github.com/tcort/markdown-link-check/issues/78) for allowing the tool to specify
-multiple files on the command line.
+The files can also be searched for and filtered manually:
+
+```shell
+find . -name \*.md -print0 | xargs -0 -n1 markdown-link-check
+```
 
 #### Usage
 
 ```shell
-Usage: markdown-link-check [options] [filenameOrUrl]
+Usage: markdown-link-check [options] [filenameOrDirectorynameOrUrl]
